However, since not all platforms will allow the entire physical address

Fix possible UB by checking for null allocating FX.
...
Namely, the global allocator API in Rust, actually only returns a null
pointer on failure, rather than wrapping it in a Result, which AllocRef
does. Since Box::from_raw(null) is direct UB, this can in theory lead to
very strange behavior.

WIP: Stop using recursive mapping.
...
Note that this is very preliminary, and I merely got my already freezing
kernel branch not to triple fault, but I would probably apply this patch
to upstream.
What is changed here, is that rather than relying on recursive mapping
for accessing page table frames, it now uses linear translation
(virt=phys+KERNEL_OFFSET). The only problem is that the paging code now
makes assumptions that the entire physical address space remains mapped,
which is not necessarily the case on x86_64 architecturally, even though
systems with RAM more than a PML4 are very rare. We'd probably lazily
(but linearly) map physical address space using huge pages.

Fix possible race condition in paranoid ISRs.
...
Additionally, because it turned out to be infeasible to rely on
link-time constants in global_asm! code, I have also converted the
interrupt handlers to naked fns. This removes the proc-macro-reliant
"paste" dependency, but inserts a tiny ud2 at the end of every ISR.
